5-42. ABC, implementation, ethics. (CMA, adapted) Plum Electronics, a division of Berry Corporation, manufactures two large-screen television models: the Mammoth, which has been produced since 2013 and sells for $990, and the Maximum, a newer model introduced in early 2015 that sells for $1,254. Based on the following income statement for the year ended November 30, 2017, senior management at Berry have decided to concentrate Plum's marketing resources on the Maximum model and to begin to phase out the mammoth model because maximum generates a much bigger operating income per unit.
